The magic of DIY + a whole lot of holes for the shelf supports...
I'm thinking about opening up the back of the receiver side a bit more, because although there's sufficient room for cooling, I didn't account for hhow much the cables have to turn. And lemme tell you, 4x14 gauge cables don't like turning much in small spaces... Believe it or not, the TiVo produces almost as much heat as the receiver, so that's why it's in the extremely large space on the right (and sitting on 4 unused/broken/sucky Atari cartridges)
